The user could also try to create the QP again if the request fails.  IMO, a 
return value of success should be sufficient for an app to determine if a 
request was successful.  Automatically reducing the inline data size 
requested by the user, but indicating success is similar to allocating a QP 
smaller than what was requested, but still indicating success.
